The Unlocking Housing at Metro Property Tax Exemption Amendment Act of 2025 aims to promote mixed-use residential development at Washington Metropolitan Area Transit Authority (WMATA) Metrorail stations in the District of Columbia. The bill proposes a 20-year property tax exemption for qualifying developments that enter into a Joint Development Agreement with WMATA, provided that at least 50% of the development consists of multifamily residential buildings and 75% of the project involves new construction or substantial rehabilitation. This exemption is intended to alleviate financial barriers that currently hinder the development of transit-oriented projects at these underutilized sites, which do not currently generate tax revenue.

The bill amends section 47-1002 of the District of Columbia Official Code to include new provisions for the property tax exemption, specifying the conditions under which it applies and clarifying definitions related to qualifying developments and Joint Development Agreements. The exemption is set to begin on January 1, 2026, and is designed to stimulate investment in housing and related amenities around Metro stations, thereby enhancing community vibrancy and supporting sustainable transit goals.
